Started in 1971, Mary Martha Thrift Store is a not-for-profit 501(c)(3) Thrift Store in Wentzville, Missouri, providing low-cost clothing and household goods to low-income individuals and families in the surrounding community.

Clothing and accessories for women, men, children, and infants.
Small household goods, including kitchenware, toys, games, small household appliances, jewelry, knick-knacks, crafts, sports equipment, pictures, lamps, collectibles and much more.

Clothing can be purchased for $4.00 a bag. Other items in the store are priced individually at a very low cost.

Volunteer Staff
We are staffed by an all-volunteer workforce. Volunteers from St. Patrick are responsible for running the store for an entire week, once every 8 weeks. We are always in need of more volunteers to both sort & price items, and to work in the store for the entire week. Volunteers usually work half or full days, 1 or 2 days every 8 weeks, depending on their availability. If you love treasure hunting for bargains, while volunteering with a wonderful group of people and helping others, this ministry is for you! We need all kinds of people! Volunteers can work as much or as little as they prefer.

All proceeds from the store, with the exception of operational expenses, are donated to non-profit organizations in our community which provide services to those in financial need or crisis situations. We provide a listing of those organizations that we support in our store. We provide a Clothing Grant Referral Program for those in need through pre-approved organizations in the community.
